Uses of Tadalafil
Tadalafil has been licensed to treat erectile dysfunction (ED
). Erectile dysfunction, also known as impotence
, can be defined as a total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Essentially, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse.
How Does It Work?
The drug works by blocking a chemical that reverses an erection by causing blood to flow out of the penis. More blood in the penis means an improved erection. For enlarged prostate symptoms
, it is thought that tadalafil probably works by relaxing the bladder and the prostate.
